AMD Radeon RX 7800M vs NVIDIA N1 16SM Comparison

The Verdict

The database contains two very different mobile graphics solutions. The AMD Radeon RX 7800M is an active mobile discrete GPU with a recorded average benchmark score of 27,883, placing it in the 73rd percentile of all GPUs. The NVIDIA N1 16SM is an integrated graphics processor (IGP) with no recorded benchmark scores, an average score of 0, and a 50th percentile ranking. Benchmark results indicate the RX 7800M is the performance-oriented part, while the N1 16SM is positioned entirely differently.

The RX 7800M sits in a competitive cluster, with its nearest rivals showing narrow margins. It trails the AMD FirePro S7150 by 0.8%, the NVIDIA GeForce GTX 980 Ti by 0.5%, and the AMD Radeon Pro W5500X by 0.3%. It leads the AMD Radeon Pro Vega 20 by 0.2%. These deltas are all under one percentage point, indicating the RX 7800M performs in a tightly packed tier where minor score variations define the ranking.

The N1 16SM has zero recorded benchmarks, so no performance conclusions can be drawn from measurements. Its 50th percentile is a default placeholder rather than a measured result. The data shows the N1 16SM is a Blackwell IGP aimed at integrated scenarios, not at competing with discrete mobile GPUs. Users seeking measured gaming or compute performance should look to the RX 7800M. Users needing a unified memory IGP with a large memory pool would consider the N1 16SM, but only from its specification profile, not from benchmark evidence.

Architecture Differences

The RX 7800M uses the Navi 32 chip built on RDNA 3.0 architecture, codenamed Wheat Nas, within the Navi Mobile (RX 7000M) generation. It is manufactured on a 5 nm process at TSMC, with 28,100 million transistors on a 346 mm² die, yielding a transistor density of 81.2M per mm². The N1 16SM uses the GB20B chip built on Blackwell 2.0 architecture, within the Blackwell IGP (N1x) generation. It is also manufactured on a 5 nm process at TSMC, but its transistor count is unknown, and its die size is 382 mm². The N1 16SM has no listed transistor density.

The RX 7800M supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1 16SM lists DirectX, OpenGL, and Vulkan as N/A, meaning no API compatibility data is recorded. The RX 7800M uses a PCIe 4.0 x16 bus interface, while the N1 16SM uses PCIe 5.0 x16. Display outputs differ as well: the RX 7800M is portable-device dependent, while the N1 16SM has a single HDMI output.

The RX 7800M has no tensor cores listed, while the N1 16SM includes 64 tensor cores. The RX 7800M has 60 ray tracing cores, while the N1 16SM has 16. The RX 7800M is the predecessor to Polaris Mobile, while the N1 16SM has no recorded predecessor. The RX 7800M launched on September 10, 2024, and the N1 16SM has a release date of May 31, 2026. The N1 16SM is a newer part by roughly a year and a half, based on release dates.

Head-to-Head Benchmarks

The database records no head-to-head benchmark entries between the RX 7800M and the N1 16SM. The winsA and winsB fields are both zero, and the headToHeadBenchmarks array is empty. This means no direct comparative measurements exist in the recorded data.

However, the RX 7800M has a full benchmark suite. In 3DMark Steel Nomad (DX12), it scores 2,994. In Geekbench OpenCL, it scores 120,778. In Geekbench Vulkan, it scores 126,668. Passmark results include DirectX 10 at 99, DirectX 11 at 176, DirectX 12 at 89, DirectX 9 at 174, G2D at 892, G3D at 17,613, and GPU Compute at 9,342. The average benchmark score across all tests is 27,883, which aligns with its nearest rivals.

The N1 16SM has no benchmark entries at all. Its average benchmark score is 0, and its percentile is 50, which is a neutral midpoint rather than a measured outcome. Without any recorded scores, the database cannot quantify its performance relative to the RX 7800M or any other GPU. The only conclusion from the head-to-head data is that no comparative benchmark exists, so any performance ranking between these two parts is unsupported by measurements.

The RX 7800M’s nearest rivals provide context. It is within 0.8% of four other GPUs, all clustered between 27,839 and 28,117 average scores. The RX 7800M’s 27,883 average score sits nearly at the center of that cluster. This indicates that in the broader GPU landscape, the RX 7800M performs on par with high-end desktop parts from previous generations, such as the GeForce GTX 980 Ti, which trails by only 0.5%.

Specification Differences

The two GPUs differ across nearly every core specification field. The RX 7800M uses GDDR6 memory with 12 GB capacity, a 192-bit bus, and 432.0 GB/s bandwidth. The N1 16SM uses LPDDR5X memory with 128 GB capacity, a 256-bit bus, and 273.2 GB/s bandwidth. The N1 16SM has far more memory capacity but lower bandwidth.

The RX 7800M has 3,840 shading units, 240 texture mapping units, and 96 ROPs. The N1 16SM has 2,048 shading units, 128 TMUs, and 24 ROPs. The RX 7800M has 60 ray tracing cores; the N1 16SM has 16. The RX 7800M has no tensor cores; the N1 16SM has 64. These numbers show the RX 7800M has roughly double the shading units, double the TMUs, and four times the ROPs, while the N1 16SM has the tensor core advantage.

Clock speeds differ significantly. The RX 7800M has a base clock of 1,295 MHz, a boost clock of 2,335 MHz, and a game clock of 2,145 MHz. The N1 16SM has a base clock of 741 MHz and a boost clock of 2,346 MHz, with no game clock listed. The RX 7800M’s memory clock is 2,250 MHz (18 Gbps effective), while the N1 16SM’s memory clock is 1,067 MHz (8.5 Gbps effective). The RX 7800M has a higher base clock and memory clock, while the N1 16SM has a marginally higher boost clock.

Pixel and texture rates diverge. The RX 7800M produces 224.2 GPixel/s and 560.4 GTexel/s. The N1 16SM produces 56.30 GPixel/s and 300.3 GTexel/s. The RX 7800M delivers nearly four times the pixel fill rate and roughly 1.9 times the texture fill rate. Floating point performance shows the RX 7800M at 35.87 TFLOPS for both FP32 and FP16 (1:1), while the N1 16SM is at 9.609 TFLOPS for both. The RX 7800M offers about 3.7 times the FP32 throughput.

The RX 7800M has no suggested PSU, and the N1 16SM also has none. The RX 7800M uses PCIe 4.0 x16, and the N1 16SM uses PCIe 5.0 x16. Display outputs are portable-device dependent for the RX 7800M and a single HDMI for the N1 16SM. The RX 7800M has a die size of 346 mm², while the N1 16SM has a die size of 382 mm², despite the RX 7800M having more transistors (28,100 million versus unknown). Both are produced on TSMC 5 nm.
